OSCAR WITTMANN, OF LINCOLN, NEBRASKA.

BArrERY-JAR.

To'aZZ 'whom t may concern:

Be it vknown that I, OSCAR WITTMANN, a citizen of the United States, and resident of the city of Lincoln, in the county of Lancaster and State of Nebraska, have invented va new and Improved Battery-Jar, or which the iollowing is a ull, clear, and exact description.

themselves become cracked, due to the eX- cessive vibration to which they are subjected.v

In a case where the plates become cracked, a short circuit will most often result, causing a quick breaking down of the cell in which the breakage has occurred, but where the cell itself becomes cracked, the electroiyte escapes thereirom, resulting inthe instantaneous breaking down ci' the cell, Vand Y consequential breaking or' the circuit, rendering the entire electric system or" the ve` hicle inoperative.

rlhis defect is to be attributed to the Jfact that the grid of the plates, the i'iller therefor, and the walls oi' the cells are ofenn tremely brittle material, the walls and base of the cell being usually of glass or hard rubber.

With this in view I have constructed a battery jar which is particularly adapted for use in connection with automotive vehicles or other adaptations in which it is subjected to eXtreme vibration, although the same might readily Vbe employed for any desired use.

Reference is had to the attached sheet of drawings as illustrating one practical einn bodiment of my invention, and in which drawings,

Figure 1 is a sectional side view taken through a battery jar or cell of a battery, showing one form of my device, and

Fig. 2 illustrates a second form thereof.

In these views the reference numeral 5 indicates the side walls of a battery jar or cell,` which in the form illustrated in Fig. 1 should be composedo a rubber compound possessing elasticity, which side walls may be provided with an embedded layer of cloth fabric 6 to stien the saine.

The bottom of the cell of a jar is formed in the usual manner with sediment furrows Specification of Letters Patent. Patented June 14 1921 Y Y Application filed April 13, 1920. Serial No. 373,656.

'posts of which extend through openings 9 formed in the cover 10, which latter is provided with the usual filling and inspection opening 11. A

t is to be noted that the cover is also constructed `of la material embodying resilient qualities, and the same is conveniently formed with a grooved down-turned edge 12, which is adapted to receive the conventional ingcompound which keys the cover in position, and provides an airtight seal for the cell.

It may be desired to construct a cell, the side walls and face of which'are formed of the usual hard rubber or glass material, and with this in view I have illustrated in Fig. Q a separate plate 13 adapted to be positioned upon the upper :tace of the door of the `Jar or cell 14, which plate is formed with ridges 7 and is constructed of a rubber or other compound employing resiliency.

It willbe appreciated by the constructions illustrated, referring more particularly to Fig. 1, that a cell made in the manner described Will embody suiiicient cushioning or resiliency to eliminate danger of a cracking of the side walls of the same, due to eX- cessive vibration.

Further, if it is desired to employ a conventional cell construction of glass or hard rubber, this may readily be done by utilizing a plate, as indicated by the reference numeral 13, and associating with the upper end of the cell, a cover such as 10.

'In both of the constructions illustrated in Figs. 1 and 2, it will be understood that the plates 8 will be capable of a small amount of shifting when in the cell upon being sub-r @bviously any size or shape of a cell or battery might be employed and numerous modiiiczttions of structure might be resorted to Without in the least departing from the scope of my claims, which read:

l. A battery jar, including side walls und a. Hoor porti-on, ridges extending upwardly from said tioor portion und within said jur, and a cover applied to said jur, said cover, side walls, and ridge portions being constructed of@d resilient materiel.

2. A battery jar, including side wells and a floor portion, ridges extending upwardly from said Hoor portion :1nd within Suid jar, und n cover applied to sind jur, seid cover, side walls and ridge portions being constructed of a resilient materiel, und reinforcing means within said side walls and iioor of the jar.

3. A battery jar, including side walls and a floor portion, ridges extending upwardly from said -Hoor portion and within sind jur, and ai cover applied to seid jur, said cover, side 'walls and ridge portions being constructed of a resilient material, and reinforcing material embedded within said side wells und :door et the jar.

A. A battery j er, including side walls and a oor portion, a, cover closing 4the upper end of seid jar, :tid cover being constructed of a, materiel having resilient qualities.

5. A battery jar, including side walls and t licor portion, a cover closing'the upper end or' seid jur, said cover being formed with down-turned edges.

6. A battery jar, and a, floor portion, a plate positioned upon said Yfloor portion and being formed with upwardly extending edges, such plate being constructed of a. material having resilient qualities.

7. A battery jar, including side walls und :t floor portion, a cover closing the upper end of seid jur, a plate formed with upwardly extending ridges upon the floor of seid jar, seid ridges sind @over being constructed of a. material embodying resilient qualities.

8. A battery jar, including side walls, and a floor portion, and resilient ridges extend- .ine u )wu-rdl 7 from the vdoor of seid nr. e l
